To all 'whom may concern I Be it known that I, BiiNJAMiN S. M CLELLAN, a citizen of the United States, and miesdent oi. Chicago, in the county of Coeli and State of lllinois, have invented certain new and useful Improvements in ll/letallio Sash; and l do hereby declare that the ollowing is a full, clear, and exact description thereof, reference being had to the accom-- panying drawings, and to the letters of ref erenee mai-lied thereon, which form 'a part of this specification,

This invention relates to improvements in metallic sash, and more particularly to that class oi metallic sash co-ninionly employed for ear windows, and coinprisii'ig a formed or bent sheet nietal shell and a llingef' Wood or other material or like character in'- closed in said shell.

It is the object of niy invention to provide an improved construction in sash of that hind consisting 4of sheet nietal and Wood or the like, and which .is designed to provide a hre-proof construction, due to the eovering of the combustible filling with a metallic exterior shell, as Well as the strength and lightness in the sash due to the use of a lilling of wood or similar material to stilfeii and etrengthenthe sheet metal shell and to orin an' inner body into which fastening screws may he inserted for uniting` the several' parts constituting the sash. into a rigid and unitary structure. i

A. further object of the invention is to provide means wherebythe glass may be readily secured in the sash and held therein by yielding pressure, in order to allow for any irregularities either in the glass or in the parte engaging or in contact with the saine, vso as to avoid liability of breakage of the glass either in inserting the saine or thereafter when the window is in use.

Fig. 5 is a ei'osesectional view showing a .-inodilied construction in the sash.

lttnterring new to Figs. l and il, in which one oit the sae-h rails or Stiles is shown, the sheet ii'ietal shell is constructed of a strip of sheet metal, which is bent or folded longitudinally to 4forin the integrally connected inner and outer side walls, and the outer edge wall, which are iiulic'ated respectively by l., and llhe eide walls l and 2 are approximately parallel with each other and are spaced a sulieicnt distance apart to give the desired thickness to the sash. lhe inner edge 4: oi' the outer wall 2 is bent inwardly toward the wall l and their rearwardly toward the wall 5:3 to provide the outer bead 3, 'which foi-ins one side ol the groove or channel for the glass ril`he inner Iside wall lis provided with an inwardlyhentorlransverse part 7, so that the inner marginal part 8 of said wall l is iiiset inwardly from the `plane of vthe niain portion of said wall l,

thereby forming a longitudinally extending recess or 'rabbet inthe outer side of said wall, intermediate the oll'set portion 7V and the inner edge ot' the lsaid side Wall, Said side wall l ie o'll less width than the wall 2 and it terminales approximately in trans verse aliiieinent with the inturned edge el. of the Wall lllithin the recess or chamber oinicd by the walls l, 2 and il is the fillingr d oit Wood liber or other suitable material. rilhe lillinvi is elioivii in Fins l l and '3 if' .1. .tin 4 u, 1 ..A b a' L l, oiga width to extend ironi near the edge of the glass i3 to the wall and is provided in its outer and inner faces with longitudinally lextending rabbets or recesses l0 and ll, the foi-nier of which is .situated at the edge of the insulator adjacent to the and the latter of which is situated at the edge of the filling adjacent to the wall 3. This construction pei'inils the lilling to he inserted into the sheet metal shell, or removed therefrom, through the opening between its Inarginal parte 4l and 8 since its thickness at either edge is n'o greater than. the width oil Said opening'. lWhen inserting the filling S) into the shell, its outer odge l2 iirst enters the opening at the inner edge of the shell, and when the side lil oi the recess l0 has passed the marginal part l oi [he outer wall 2, the fillingT is inoved laterally to permit the side ldof the recess ll lo pass the inargii'ial part 8 oi the Wall l. The recesses' l0 andl'l also provide dead air spaces between the sides of the filling and the walls l and 2. The marginal parts Ll and 8 of the side walls raison of the construction described in -teward the filling` 9 and vforms the inner side 1 and 2 may be connected in any preferred manner, but, as shown in Figs. 1 and 2, they are joined as shown and described in my application for Letters Patent Serial No. 561,954, filed May 18th, 1910, that is to say, by meansy of' locking strips or plates l5 extending transversely of the inner edge of the filling and each having flanges 16 and 17 which hook over the marginal parts 1 and 8, respectively, and serve to prevent the side walls from spreading apart. Said strips, as shown, are countersunk in recesses 18 in the edge ofl the filling and are secured thereto by woodscrews 19, which extend through the strip and into the edge of the filling. A removable sheet metal strip 20, 'forming a bead, is secured to the inner face 'of thr sash and extends inwardly therefrom,; with its inner edge flush with the edge of the bead 5, to provide theinner wall of the channel or recess for the glass. Said strip 20, as shown in Figs. 1 and Q, has its outer marginal part seated in the recess .or rabbet formed by the offset marginal portion S of the wall l, and bears against the flanges 17 of the locking plate 15. Vood screws 21 extend through said stri Q0 and through the flanges 17 and marginal part 9) of the wall 1, and into the filling E); said screws serving to rigidly lioin said parts.v The strip 20, in its part which projects inwardly beyond the body of the sash, and which forms the inner bead, is bent or inclined inward toward the outer bead 5, and its marginal part 22 is bent or extended rearwardly wall of the groove or channel for the glass. The marginal parts 4 and 22 of the wall 2, and strip 2O are inclined or arranged at an angle to each other, so thatthe channel for the glass is somewhat wider at its inner than at its outer part, in order to prev nt the putty 23 from working out oit' the eiiannel. Then the bead, formed by the strip 20, is brought up to place by the screws 21, 'its marginal part 22 compresses the -putty firmly against the glass but with an even pressure throughout the length of the bead.

the sheet metal paris constituting the inner and outer beads, the marginal parts et and 22 of said beads are made elastic or yielding, so that the glass is held by a yielding pressure, and liability of breakage ott the same is obviated. Flexible weather strips 24 Jfor the sash are shown as secured to the outer marginal face or edge of' the sash, in the usual manner, by means of an angle bar 2.5 and screws 26, which pass through one flange of the bar, the strip and the wall Band into the filling 9.

The filling in the structure described not only prevents the passage of heat and cold through the sash rails and stiles, but it also provides a firm anchorage for the attaching screws for the beads and weather strips, without necessitating the placing of the screws at predetermined points, as is required where machine screws are employed with abutments to receive the screws.

If preferred, one continuous locking plate 2T may be employed, as shown inl Figs. 3 and 4, which plate extends the full length of the ,rail or stile, in contact with the inner edge of the filling @and has oppositely directed flanges 28 and 29 thereon, which engage the marginal parts i and 8 of the walls 1 and 2, as described, with reference to the plate 15. Said continuous plate 27 is shown, as attached to the fillinoby wood screws 19, as are the separate locking plates 15,'shown in Figs. 1 and 2'. l

In Fig. 5 I have' shown another form of construction embodying the same general features hereinbcfore set forth. `In this instance,

-the metal shells of the sash rails and stiles have their outer walls 34, inner walls 35, inner edge wall 36 and outer edge wall 37 formed .from a single piece of' sheet metal bent into tubular form, as shown in said Fig. 5. In this case the lateral edges of the metal strip or sheet are preferably arranged to meet in the outer edge wall 37 of the shell and are welded together, or otherwise joined at 38. Before said edges of the sheet are turned in and joined, however, the filling 39 is insert-ed -from the outer edge of the sash and then the edges of the metal are folded in and secured together, thus inclosing the filling within the sheet metal shell.

As shown in Fig. 1 of the drawings, I have provided a sash lock 11E-3 which is placed,

directly against the inner side wall 1 of the shell and is secured in place by means of screws 114 and 45, which extend through the said side wall 1 and through a wooden abut-- mentblock L16 into the filling 9. Said abutment block is seated in the recess or rabbet 11 of the filling, and fills the space between the inner face of the filling and the said inner 'wall 1 ot' the shell. When a filling of' rectangular form is employed, as shown in Fig. 5, the abutment block A1G is omitted.

The outer edge walls 3 of the shell, in the construction shown both in Fig. 1 and Fig. 5, have a longitudinal groovc--1f7 therein to prevent the sash contacting with the inclined bearing plate L1% for the weather strip 24.

` In a sash ma'de as described, the sheet metal parts, bent into U-form to constitute `the holding beads t'or the sash, are elastic or yielding in character, and act to hold the glass in place with a yielding pressure, so as to avoid liability of breakage of the glass.-

isa

Moreover, the construction described, in the cured together and to the filling by a 'single i series of screws. The filling of wood orthe like enables ordinary wood screws to be used for attaching the removable sheet metal beads and the side weather strips to the sash, and obviates the necessity for using abutment blocks having screw threadedl apertures, such as are necessary when Inachine screws are employed to join the parts. Moreover, when the glass has been placed in the sash with its edges embedded in putty, the removable bead, by reason of its elastic` or yielding character, due to its exible inner flange 22, may be drawn up tf''place7 without causing undue stress onthe glass.

The present application is a division of my hereinbefore mentioned application, Serial No. 561,954, filed May 18, 1910.

AMany of the details ot the construction shown may be varied or omitted without departing from the spirit of the invention, and I do not desire to be limited to such details, except as pointed out in the appended claims.

I claim as my invention:
